Combining high security with contemporary design, the Yale Digital Door Lock (DDL) has been developed for the discerning individual seeking the very latest in convenience, functionality and style. Ideal for residential situations, Yale Digital Door Locks offer three access solutions:

• YDM3109: 1. PIN code 2. Proximity card (up to 40 cards) 3. Key
• YDM4109: 1. PIN code 2. Fingerprint scanner (up to 20 fingerprints) 3. Key

For security, when there is a chance of exposing your code to others, the Yale Digital Door Lock “scramble code” allows you to add meaningless numbers before or after the code. Furthermore, if a card is lost,you can simply re-register the cards you want to remain active and all other cards are automatically deleted. As an additional security measure, an 80 dB alarm goes off if anyone attempts to damage the lock or force the door open.

Beyond the security of the Yale Digital Door Lock are numerous safety features, such as anti-panic egress. For convenience and in case of emergency, the door is automatically unlocked whenever the inner lever handle is used. For child safety, the button on the inner lever can be set so it must be pressed to open the door.
